You might try bathtub caulk to seal the penetrations. However, if
you've accumulated that much water in the box, I would recommend you include
provisions to drain it. A couple of small (quarter-inch) holes in the
bottom of the box should do it. You can find screening material to apply
across the opening; the material will keep critters from establishing a home
inside the box.
